The myelin sheath, an insulating layer around the axon of a neuron, is mainly made up of H20 (40%); the dry mass of myelin is made up of mostly lipids (70 - 80%), and the rest is proteins (30 - 15%). There are three types of myelin protein, one of which is myelin basic protein. The lipid that mostly makes up myelin is called galactocerebroside.

What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
What does the sheath do around the axon?
Protects the axon. The "Myelin Sheath" serves as an insulator to protect nerves.
What vitamin maintains the myelin sheath that surrounds and protects the nerve fibers?
Vitamin B12
What part of the neuron keeps the nerve healthy and protects them at the same time?
Myelin Sheath
What increases the speed of the transmission?
Myelin Sheath Myelin Sheath
What are schwann cell nucleus'?
myelin sheath peace.love.faith
What increases the speed of impulse transmission?
Myelin Sheath Myelin Sheath
It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
The layer of lipid around an axon is called?
Myelin sheath
What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
Imagine two neurons one is wrapped with a myelin sheath and has a large diameter the second neuron has no myelin sheath and a narrow diameter which of these neurons conducts a nerve impulse more rap?
Neurons send their impulses up and down the spinal cord. The myelin sheath is the coating around the spinal cord that protects it, and works to better conduct the signals along the cord. A neuron that has no myelin sheath will have a harder time conducting signals than one that is covered by the sheath.
What is adrenomyeloneuropathy?
Adrenomyeloneuropathy is a progressive, X-linked, neurological disorder which deteriorates the myelin sheath which protects the spinal cord.
